When a Windows 10 Pro key still makes sense

Windows 10 continues to work even after the end of support, but it no longer receives any regular security updates. For a main computer used in production, that is a real risk. However, there are situations in which a Windows 10 Pro key remains a sensible choice.

This applies above all to older hardware that does not meet the requirements of Windows 11, for example due to a missing TPM 2.0. For offline devices, isolated specialised applications or test systems, Windows 10 can also remain the pragmatic choice.

When Windows 11 is the better choice

  • Compatible hardware available. If your device meets the Windows 11 requirements, switching to Windows 11 Pro is the future-proof path.
  • Main computer used in production. On a device used every day, ongoing security updates are important, which speaks in favour of Windows 11.
  • New purchase planned. For a new PC, always go straight to Windows 11; a Windows 10 key would be the wrong investment here.
  • Not sure? Check your hardware. Microsoft's PC Health Check shows in just a few minutes whether Windows 11 is possible.

Häufige Fragen

Is a Windows 10 Pro key still worthwhile?

Only to a limited extent. Since October 2025, Windows 10 no longer receives regular security updates. A key remains useful mainly for older hardware that does not support Windows 11.

Can I switch from Windows 10 to Windows 11?

Yes, if your device meets the Windows 11 requirements. The switch is possible as an in-place upgrade, without a reinstallation and usually without data loss.

Does Windows 10 still work after the end of support?

Yes, it keeps running. However, there are no longer any regular security updates, which poses a risk on a device used productively.
